Answer:
x = 4
y = -3
Step-by-step explanation:
We can use substitution, elimination, or graphically.
Step 1: Rearrange first equation
2x + 4y = -4
2x = -4 - 4y
x = -2 - 2y
Step 2: Rewrite systems of equations
x = -2 - 2y
3x + 5y = -3
Step 3: Substitution
3(-2 - 2y) + 5y = -3
-6 - 6y + 5y = -3
-6 - y = -3
-y = 3
y = -3
Step 4: Find <em>x</em> using <em>y</em>
2x + 4(-3) = -4
2x - 12 = -4
2x = 8
x = 4
Graphically:
Use a graphing calc and analyze where the 2 lines intersect.
The answer is going to be 11.98. hope that helped
Answer:
x = +3 , y = +3
Step-by-step explanation:
Just solve for x in eq1
to become: x=6-y
then substitute it in eq2
6-y-y=0
6-2y=0
2y=6
y=+3
And finally substitute the value of y in any eqs to find the value of x.
I hope that it's a clear explanation.
